This moth can hear higher-pitched sounds than any other animal on record
The greater wax moth detects ultrasound up to roughly 300 kHz, the highest frequency sensitivity ever measured in an animal. That range comfortably exceeds the loudest bat echolocation calls, which top out near 212 kHz, giving the moth an early-warning system tuned beyond its predators' current sonar. Its eardrum is barely half a millimetre across.
